How to debug `rails s` when it hangs?

I have strange problem. After running rails s on some project, the script hangs with no output and no logs. How can I debug it and inspect what's going on? I use rvm with ruby 1.9.2.

If you want to dig a big deeper, you can use utilities such as "strace" or "dtruss" to see what files are being opened.

Linux:
$ strace rails s

Mac:
$ sudo dtruss rails s

You might not know what all of the output means, but you might get an idea if something is missing.

check log/production.log to find the last file or line of code executed and try to figure out what went wrong.
